Richard Simmons

Grab yourself a wig, some short shorts, and a tank, and you already have the makings of a Richard Simmons costume. Carry a portable radio with you on Halloween [2] that plays hits from the '50s — you'll have everyone Sweatin' to the Oldies!

Cyclist

Spend a little time searching a secondhand clothing shop and your garage. Before you know it, you'll soon have the makings of a cyclist costume.

Go For the Gold

Cover yourself in medals and go as Olympic swimmer Michael Phelps [3]. Novelty medals are cheap and easy to find, or you can make your own with ribbon and gold craft paper. Don a spandex bodysuit, or wear black leggings with a red, white, and blue jacket or Olympic-themed shirt. Finish the look with a swim cap and goggles.
